A virtual appliance update mechanism detects when an update to a corresponding workload is made, and makes automatic corresponding changes to the virtual appliance to reflect the update to the workload. In one specific implementation, the virtual appliance update mechanism determines that configuration units corresponding to the update to the workload are present in a knowledge base of configuration units, and automatically updates the virtual appliance with the configuration units corresponding to the update. In this manner a virtual appliance may be automatically updated based on an update to a workload, thereby assuring the virtual appliance reflects the current state of the workload.

Software tool and method for updating a virtual appliance

A virtual appliance construction tool allows a user to select using a user interface functional information for a virtual appliance to generate a functional model of the virtual appliance. A knowledge base of configuration units is then queried to determine which configuration units are needed to satisfy the functional model. Note the configuration units include not only functional information, but virtualization information as well. The configuration units are then packaged into a virtual appliance blueprint, which is used to generate a certified virtual appliance. In this manner the user need not have extensive knowledge or training regarding virtualization because the virtualization information is selected automatically based on which configuration units provide the function specified by the user.

In an embodiment, a unit workload comprises an average processor speed and an average memory amount required by execution of images. If an integer multiple of the average processor speed required minus a free processor speed at a source computer is greater than a first threshold amount, an integer multiple of the average memory amount required minus a free memory amount at the source computer is greater than a second threshold amount, the integer multiple of the average processor speed required minus a processor speed requirement of a source image at the source computer is less than a third threshold amount, and the integer multiple of the average memory required minus a memory requirement of the source image at the source computer is less than a fourth threshold amount, then deployment of the source image is moved from the source computer to a destination computer.
